Eibach's Stage 2 system pairs Pro-Truck Coilover 2.0 units with rear sport shocks, so a 2014-2018 Silverado 1500 2WD gets height-adjustable front coilovers and a matched rear damper setup from one kit. The threaded body is 2.0 inches, and the manufacturer describes 46mm pistons, a monotube design with nitrogen-filled variable force valving, and anodized 6061-T6 billet aluminum coilover mounts. This is the kit for owners who want to fine-tune front ride height, not just drop a fixed-height spring in place of the factory strut.
The main reason to pay for this over stock or a budget lift is control over the front end. The threaded body lets you set front height in small steps, and the manufacturer positions the kit for improved on- and off-road handling. The front springs are ERO off-road race springs on the manufacturer's Pro-Truck Coilover 2.0 listing, and each unit is individually dyno tested for matched performance and reliability. Searching for a 2014-2018 Silverado 1500 2WD threaded coilover, Pro-Truck 2.0 front strut, or adjustable ride height 2WD kit? This is the Stage 2 configuration with sport shocks, which differs from the reservoir-shock Stage 2R.
The manufacturer lists the Stage 2R as a separate part, E86-23-032-02-22, which keeps the same threaded front coilovers but swaps the rear for reservoir-style sport shocks.
The manufacturer lists this kit as a pair of front coilovers plus rear shocks, so the rear end is covered without buying additional parts.
The manufacturer's product page links installation instruction sheets for this part number.
The manufacturer describes this kit as an easy bolt-on installation, but it replaces the front struts and involves a preloaded upper control arm, so it is best suited to a mechanic or an experienced DIYer with a hoist and jack stands. Per the manufacturer's Pro-Truck Coilover 2.0 install sheet, use a hoist and screw jack to speed the job, never use an impact wrench on the piston rod nuts, and install springs with the Eibach logo upright. The upper control arm can swing upward when the nut is removed, so hold it with a pry bar. Tighten to factory torque specs, then have the alignment, tire and fender clearance, brake line routing, and ABS sensors checked after installation.
